(figs.20, 43, 68, 118, 119, 178, 231, 232 and 233)

Diagnosis: This species resembles I. cretaceus (Faust) and is distinguished by the following characters: Rostrum deeply impressed at the middle dorsally, median furrow short, broad, oval, with ends rounded. Prothorax as long as broad, upper surface shallowly punctate. Antennae with first funicle segment 1.3x as long as the second. Elytra with humeral fold not projecting, fourth, fifth and sixth intervals with an impression at the posterior declivity. Male genitalia with shaft of spiculum ventrale 1.2x as long as median lobe, apex of manubrium rounded and capitate, apophyses 0.77x as long as median lobe.

Description: Colour black with pale grey or black vestiture. Head only 0.8x as long as rostrum, upper surface convex, with shallow, scattered punctations. Rostrum deeply impressed at the middle dorsally, 1.05x as long as broad, its breadth at anterior margin 0.73x as that of posterior margin; median furrow short, broad, oval with either ends rounded; lateral carinae distinct throughout rostrum; sides narrowed towards anterior margin; scrobes uniformly broad, rounded at either ends and broadest towards eyes. Eyes dorsal and convex (figs. 20 and 43). Antennae reddish brown; scape abruptly clavate; funicle having its first segment 1.3x as long as the second, third and fourth subequal, fifth and sixth equal, seventh broadest; club conical and hairy (fig. 68). Prothorax as long as broad, its breadth at middle 1.1x as broad as posterior margin; sides rounded; anterior margin only 0.86x as broad as posterior margin, truncate dorsally and acute laterally, posterior margin subtruncate; upper surface shallowly punctate and interspaces obscurely granulate. Legs with hind tibial apex without any dense, golden yellow hairs. Elytra broadly ovate, with basal margin strongly raised, its external angle acute, humeral fold present but not projecting; not at all impressed on the declivity, apices separately pointed but not truly mucronate; stria shallowly punctate; intervals broad, convex and raised, fourth, fifth and sixth with an impression at the posterior declivity; elytral vestiture with predominant scales subrectangular to subovate, yellow, with 9–10 ridges (fig. 118), less predominant, more elongate, brown, broadened towards apex, with 3 ridges (fig. 119).

Male genitalia: Aedeagus with median lobe membranous at middle, in profile arcuate at base, its apex pointed, length: breadth ratio 9:1; apophyses 0.77x as long as median lobe, apices truncate (figs. 231–232). Tegmen with dorsal piece 7x as broad as basal piece; parameres long, pointed at apices; manubrium gradually thickened towards rounded apex, 0.5x as long as shaft of spiculum gastrale (fig. 233). Spiculum gastrale uniformly thickened, narrowed towards either ends, its apex bent at acute angle and rectangular; basal prongs subequal, their apices rounded, and each prong with a wavy base (fig. 178).

Length: male, 8.55 mm; Breadth: male, 2.73 mm.
